Applications Woodward’s complete line of Fuel Metering Systems or “fuel skids” incorporates the components needed for DLE engine operation for industrial aeroderivative gas turbine platforms. They represent the latest in a long line of fully validated, highly reliable systems made available to the market at cost-effective prices. These simple, drop-in solutions are typically applied to electrical power generation, gas compression, and mechanical drive system processes. These metering system products perform with all-electric valves and instrumentation, eliminating the need for hydraulic or pneumatic input. Woodward has established a pedigree of highly accurate flow metering valves and instrumentation as well as highly effective system level solutions. Fuel skid users can benefit from Woodward’s expertise and can expect high reliability, quality, service, and performance from these products.
Description Woodward fuel metering skids consist of multipath metering legs, each individually controlled by a Woodward metering valve to the various combustor manifolds or cans. For each flow path, high-accuracy, high-bandwidth pressure-sensing transducers are incorporated in the fluid path to measure pressure. Temperature-sensing devices are also placed within the flow path to transmit the fuel temperature to the turbine control. The combination of these signals with the engine flow demands to each leg allow the turbine control to compute the valve positions necessary to provide the correct flow to the engine. When integrated shutoff valves are incorporated, the skid can isolate the pressure supply from the engine in the event of a system shutdown. Vent connections are provided in various locations to allow a customer-connected exhaust gas stack.

Compliance Woodward is exceptionally competent in conforming to and understanding the industrial hazardous location compliance and installation practices for most regulating entities.
Common P1 Common P1 is a cost reduction feature that utilizes a compensation model to optimize the skid performance to a particular engine flow profile. The model algorithms simultaneously predict multi-path pressure losses in the piping to reduce the number of pressure-sensing elements required in the system from as many as 20 sensors to 12. The model maintains system-sensing redundancy and system pressure measurement accuracy. Ask Woodward how this solution can be applied to your system for pressure-sensing cost reductions.
